This study comprehensively examines the implementation process of domestic landscape policies since enacting the “Landscape Act,” which aims to develop policies for sustainable national landscape formation and respond to rapidly changing policy environments. The research seeks to propose future policy directions while analyzing policy achievements and limitations. Specifically, from a policy analysis and evaluation perspective, this study aims to understand landscape policies’ formation and implementation process and derive their outcomes and limitations by analyzing implementation results. To this end, a Delphi survey was conducted with 24 landscape experts three times. While the study’s temporal scope begins with the 2007 enactment of the “Landscape Act,” it also examines significant systems, plans, and projects related to landscape management implemented from the early 1990s to 2007. The content scope encompasses the landscape management system presented in the “Landscape Act” and related implemented policies.
